  "content": "Chandrasekharan J., a 58-year-old plastic technology expert from Chennai, has developed an innovative non-electric natural water purifier to resolve severe drinking water shortages across rural India. Operating under his venture Watsan Water Filters, the self-described accidental entrepreneur has created a filtration system that functions entirely without electrical power or batteries. To date, this non-electric purifier has reached nearly 5 lakh families across underserved regions where people were previously forced to consume contaminated water or pull their children out of school due to water scarcity.\n\nThe Journey From Corporate Career to Social Innovation\nBefore turning to social entrepreneurship, Chandrasekharan spent nearly 35 years working in a major corporation as a plastic engineering professional. The turning point arrived when he was around 45 years old, during a visit to rural Tamil Nadu for temple restoration initiatives. In these villages, he witnessed firsthand how communities suffered from an acute lack of clean water. The absence of basic water facilities in schools and restrooms severely disrupted daily life, compelling parents to withdraw their children from formal education. Deeply moved by this reality, he determined to design an affordable, accessible water treatment system that required no power source.\n\nHow Terafil Nano-Technology Purifies Water Without Electricity\nThe core innovation of the Watsan purifier lies in its utilization of the Terafil nano-technology developed by CSIR-IMMT. The filtration unit employs a specialized nano-candle constructed from nano-clay particles. As raw water or collected rainwater passes through the candle, the dense nano-structure physically captures micro-organisms, suspended silt, and elevated iron levels at the outer surface. Simultaneously, the system preserves vital minerals present in the water and maintains optimum pH balance without adding synthetic chemicals.\n\nZero Water Waste and Zero AMC Maintenance Advantages\nUnlike traditional Reverse Osmosis (RO) purifiers that reject large volumes of water during treatment, this natural filtration system operates with zero water waste. It rapidly converts turbid surface water and rainwater into safe drinking water within minutes. Furthermore, the unit requires no Annual Maintenance Contract (AMC), eliminating recurring service expenses for lower-income households. Its lightweight and durable construction also makes it simple to transport and install in remote locations.\n\nShowcase at Global Aqua Expo and Nationwide Reach\nDuring the three-day Global Aqua Expo held at Bharat Mandapam in New Delhi, Chandrasekharan J. demonstrated the operational capabilities of his natural purifier to industry leaders and visitors. The practical solution garnered widespread praise for its efficacy and low operating cost. Today, over 500,000 units are actively serving families in water-stressed areas across Rajasthan, the North East, Jharkhand, Bihar, West Bengal, and Tamil Nadu, helping curb waterborne illness while enabling children to remain in school.\n\nWhat this means for you\nAcross India: This non-electric filtration technology offers a sustainable and affordable solution to ensure safe drinking water in remote and off-grid rural communities.\n\nFor Rural Families: Clean drinking water can be produced instantly without the high maintenance costs and water wastage of traditional RO purifiers, preventing waterborne diseases and helping children remain in school.\n\nQuestions & Answers\n\n1. What technology does Chandrasekharan J.'s water purifier use?\nIt uses CSIR-IMMT's Terafil nano-technology, which relies on filter candles made from nano-clay particles.\n\n2. Does this water purifier require electricity to operate?\nNo, it operates entirely without electricity or batteries.\n\n3. How does this purifier differ from traditional RO filters?\nUnlike traditional RO systems, it causes zero water waste, retains essential minerals, balances pH levels, and requires no Annual Maintenance Contract (AMC).\n\n4. What is the name of Chandrasekharan J.'s company and where are the filters used?\nHis company is named Watsan Water Filters, and over 5 lakh filters have been distributed across states like Rajasthan, the North East, Jharkhand, Bihar, West Bengal, and Tamil Nadu.\n\n5. What inspired Chandrasekharan J. to invent this filter?\nAround age 45, while visiting Tamil Nadu villages for temple restoration work, he noticed children dropping out of school due to severe water shortages in schools and toilets, inspiring him to create a non-electric solution.\n\nInspiration & Lessons\n• Turning Vision into Action: Rather than just feeling sympathetic about rural water shortage during his temple visits, Chandrasekharan took concrete action to build a solution.\n• Applying Professional Skills for Social Good: He leveraged his 35 years of expertise in plastic engineering to address a critical basic human need.\n• Designing for Accessibility: True innovation focuses on user needs by eliminating dependencies on electricity and costly maintenance agreements.\n• Impacting Lives Beyond Business: Providing clean water directly boosted school attendance, demonstrating how engineering solutions can resolve wider social challenges.",
